Hi Anwar,
Try adding a reference to your jquery directly in your web resource the button is hooked into:
var JScriptWebResourceUrl = “../WebResources/new_JQuery”;
var xmlHttp = new ActiveXObject(“Microsoft.XMLHTTP”);
xmlHttp.open(“GET”, JScriptWebResourceUrl, false);
xmlHttp.send();
eval(xmlHttp.responseText);
I hope this helps. If my response answered your question, please mark the response as an answer and also vote as helpful. Michael Mayo
